Why these three power banks
A thru-hike battery is light, USB-C, and big enough to reach town. That is the whole job. Headlamps and messengers have their own lists.
Nitecore NB10000 is first: 5.3 ounces, 10,000 mAh, the bank a lot of a PCT class already carries. Nitecore NB20000 is the Premium Pick when the carry is longer. Nitecore NB Air is Best Value: 5,000 mAh at 3.14 ounces, 18W USB-C, IPX7.

Nitecore NB10000 Power Bank
What it is
Card 10,000 mAh · 5.3 oz · ~$80 · USB-C. CleverHiker kitchen-scale class: just over 5 oz for recent NB10000 gens. Slim carbon/polycarbonate brick; dual USB-C on current gens; pass-through charging on reviewed units.
HA 2026 PCT — Battery Packs: vast majority carry a pack; median thru size 10,000 mAh

Nitecore NB20000
What it is
Card 20,000 mAh · 10.2 oz · ~$120. HA packing lists cite Nitecore NB20000 Gen3 at about 10.26 oz / 291 g, dual USB-C, pass-through. Roughly double the cells of the NB10000 at roughly double the weight.
Halfway Anywhere — PCT packing list / UL gear list (Nitecore NB20000 Gen3 ~10.26 oz)
When town is five days out or multiple devices share one bank. Heavier than NB10000; HA author prefers one 20k over two unreliable 10ks in packing notes. Still a battery pack, not solar.
HA packing list — NB20000 for long charger-free sections
HA 2026 PCT — packs default over solar
Card claim — twice the cells when the carry is longer
Why it's on the top three
Premium Pick: double capacity for long dry stretches at a known UL weight.
